git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler fixes from Thomas Gleixner: "A set of scheduler updates: - Prevent PSI state corruption when schedule() races with cgroup move. A recent commit combined two PSI callbacks to reduce the number of cgroup tree updates, but missed that schedule() can drop rq::lock for load balancing, which opens the race window for cgroup_move_task() which then observes half updated state. The fix is to solely use task::ps_flags instead of looking at the potentially mismatching scheduler state - Prevent an out-of-bounds access in uclamp caused bu a rounding division which can lead to an off-by-one error exceeding the buckets array size. - Prevent unfairness caused by missing load decay when a task is attached to a cfs runqueue. The old load of the task was attached to the runqueue and never removed. Fix it by enforcing the load update through the hierarchy for unthrottled run queue instances. - A documentation fix fot the 'sched_verbose' command line option" * tag 'sched-urgent-2021-05-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/fair: Fix unfairness caused by missing load decay sched: Fix out-of-bound access in uclamp psi: Fix psi state corruption when schedule() races with cgroup move sched,doc: sched_debug_verbose cmdline should be sched_verbose

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking fixes from Thomas Gleixner: "A set of locking related fixes and updates: - Two fixes for the futex syscall related to the timeout handling. FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and because it's not set the time namespace adjustment for clock MONOTONIC is applied wrongly. FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its always a relative timeout. - Cleanups in the futex syscall entry points which became obvious when the two timeout handling bugs were fixed. - Cleanup of queued_write_lock_slowpath() as suggested by Linus - Fixup of the smp_call_function_single_async() prototype" * tag 'locking-urgent-2021-05-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: futex: Make syscall entry points less convoluted futex: Get rid of the val2 conditional dance futex: Do not apply time namespace adjustment on FUTEX_LOCK_PI Revert 337f13046ff0 ("futex: Allow FUTEX_CLOCK_REALTIME with FUTEX_WAIT op") locking/qrwlock: Cleanup queued_write_lock_slowpath() smp: Fix smp_call_function_single_async prototype
